IMPROVEMENT IN HORSE HAY-RAKES.

IIO ALL WHOM IT MAY` CONOERN: I

Be it known that I, THOMAS N. HENDERSON, of Jackson, in the county of Jackson, and State of Michigan, have invented a new and useful Improvement in -Revolving Horse Hay-Rakes; and I do hereby declare that. the following is a full, clear, and exact description thereof. which will enable others skilled in the nrt to make and use `the saine, reference being had to the accompanying dra-wing, formingapartoi' this specification, in whichl l 'Figure l is a perspective View of my improved horse hay-rake.

Figure 2 is a vertical cross-section ofthe same.-

Similar letters of reference indicate like parts.

My invention' has for its object to furnish an improved revolving horse hay-rake, the parts of which are so constructeikand arranged that they muy be'adjusted to hold the rake-headl at any desired angle while raking, and that the rake-head may be at all times completely under the control ofthe operator. i

And i-t consists, rst, in the combination Aof the adjustable drop, revolving cross-bar, and operating lever with each otherhand Withthe handles and teeth of the rake; second, in the combination of the adjustable springs with the draught-bars, knees, and studs of the rake; and, third, in making each draught-bar and handle in one piece; the whole being constructed andarranged as hereinafter more fully described.

H is the rake-head shaft, which revolves in bea-rings j attached to the lower ends of the knees .I in the ordinary manner. The teeth I are made and attached to the shaft H in the usual way. B are iron studs passing through and secured to the shaft H for the lower ends ofthe adjustable steel springsA to rest upon in holding the rake-head. These studs B, when the rakehead is revolved, strike against and press out the lower ends of the steel springs A, which by their elasticity, as soon as the studs have passed, spring back to their former position and holdthe rake-head steadily while raking. G is the draught-har, and G isthe handles of the rake, whichare made in one piece, as shown i'n figs. 1 and 2. The forward ends of the draught-hars G are connected by cross-bar, F, and the rear ends ot" the handles G are connected by a cross-bar or roll, R.'as shown in fig. 1. To the under sides of the bars G nre iirmly attached the upper ends of the kneesJ; and the connection is further strengthened by the braces N, as shown in the drawings. A are the steel springs, the upper ends ot` which are secured both to the knees J, and' to the draught-hars G by bolts which pass through the said knees and draught-hars, and through slots inthe upper ends et' the said springs A, as shown in figs. 1 and I2, so that the position of the springs may he reguiated to give the desired pitch to the rake-teelh when operating. The springs A, just below the lower slots, are twisted or turned o`ne-quarter around, so as to bring their lower ends into the proper position to act upon the studs B K is a rolling crss-bar, the ends of which are pivoted to the handles G', and to its central part is attachedthe upper end of the adjustable drop C, by a thumb-nut and bolt which passes through the said rolling cross-bar K, and through a slot in the upper part of the drop C, as shown in g. l. By this construction the-drop C may be adjustedin connection with the adjustment ofthe springs A., so as to hold the rake-head Steady and at 'the proper angle while raking. E is the operating lever, one end of which is attached to the rolling` cross-bar K, and the other end projects out in the rear oi' the cross-bar R in such a'position as to be easily reached by the operator when it is desired to remove the drop-Oliven] the teeth I to allow the rakelhead to revolve and discharge the collected hay. The free end of the lever Ellis kept within proper limits by the wire loop D, which projects downward fromV the cross-bar R to which it is attached, as shown'in iig. 1.

Having thus described my invention, ,I claim as new, and desire to secure by Letters Patent- A The combination of the adjustable drop C, rolling cross-bar K, and operating lever E, with each other), and with the handles G and teeth I of the rake, substantially as herein shown and described, and for the purpose set forth.
